Polysaccharides
Les polysaccharides sont des composés organiques formés par l'union de plusieurs monomères, liés entre eux par des liaisons glycosidiques pour créer de grandes molécules souvent ramifiées. Ces glucides complexes jouent des rôles cruciaux dans diverses fonctions biologiques, y compris le stockage d'énergie, le soutien structurel et la communication cellulaire. Dans cette section, vous trouverez une gamme variée de polysaccharides essentiels pour la recherche en biochimie, biologie moléculaire et glycosciences. Ces composés sont vitaux pour l'étude des voies métaboliques, des structures de la paroi cellulaire et du potentiel thérapeutique des glucides. Chez CymitQuimica, nous proposons des polysaccharides de haute qualité pour soutenir vos recherches scientifiques, garantissant précision et fiabilité dans vos résultats expérimentaux.

CAS :A fucan sulphate found in brown marine algae (Phaeophyta-typically Fucus vesiculotus, Ascophyllum nodosum, Alaria and Lessonia nigrescens (illustrated) and has been shown to have anticoagulant activity. The main constituents are α-1,4 and α-1,2 linked L-fucose sulphates although galactose also occurs and there are many variations of the basic structure found in different species of Phaeophyta. The fucose content is approx. 26.2% and it also contains galactose (approx. 13.0%), uronic acid (approx. 13.0%) and sulfate (approx. 29.1%).

CAS :Chitosan from fungal cell walls. It is made by treating cell walls of fungi (agaricus bisporus) with sodium hydroxide.Viscosity typically 20-100 mPa.sCouleur et forme :PowderCellulose - Arbocel
CAS :Cellulose is a linear polysaccharide of β 1-4 linked glucose residues. The polysaccharide chains are bundled as microfibrils in cell walls and provide the essential structural components within growing plants. Each microfibril exhibits a high degree of three-dimensional internal bonding resulting in a crystalline structure that is insoluble in water, resistant to reagents and very strong.Couleur et forme :PowderHyaluronic acid from Bacteria
CAS :Please enquire for more information about Hyaluronic acid from Bacteria including the price, delivery time and more detailed product information at the technical inquiry form on this pageDegré de pureté :(%) Min. 90%b-D-Glucan-from piptoporus betulinus
CAS :This β-glucan contain D-glucose residues with β-1,3 links and b-1-6 side branches. The frequency, location, and length of the sidechains may play a role in immunomodulation. Differences in molecular weight, shape, and structure of β-glucans can also affect the differences in biological activity. The water-soluble β-D-glucan is extracted from fruiting bodies of Piptoporus betulinus by hot aqueous extraction, followed by freeze-thawing and dialysis. Methylation analysis and NMR spectroscopy, indicated the presence of a β-D-glucan with a main chain (1,3)-linked, substituted at O-6 by single glucose residues.
